Arduino Digital FM Radio (TEA5767): Hi! In this project I will show you how to easily use TEA5767 module and build your own digital FM Radio! Stuff that you will need: Arduino uno TEA5767 Radio module Nokia 5110 display (pcb version) 2x Push Button Optional, if you want t…
Combine the Si4844-A10 analog-tuned radio receiver with an Arduino to make a full-featured multiband radio.
FM Radio : Recently, I came across RDA5807 module which is an FM Radio Tuner in a very tiny package. It is very cheap and uses I2C protocol for communication which means that only two wires will be required to talk to the IC. Less wiring! My mom used to listen…
Simple Arduino-based "World Band" radio receiver with very good characteristics.
Make an Arduino FM Radio! (using TEA5767): Hi guys from Instructables, In this tutorial i'll show you how to make a FM digital Radio easily using arduino uno (or any other arduino board), and the TEA5667 Fm Radio module, and audio amplifier and a LCD 16X2. Let´s start !
The sketch for this project can be found on my GitHub page here. My last blog used the little FM radio, TEA5767, with a two line LCD and keypad display. I felt that it was a little clumsy and …
Build a great sounding FM radio with a cool display using an Arduino Nano and the SparkFun Si4703 FM tuner breakout.
Make Your Own FM Radio: In this project I will show you how to transform a TEA5767 and an Arduino Pro Mini into a functional and decent looking FM Radio through the help of a couple complementary parts. Let's get started!

This is a project of Radio Receiver LW/MW/SW Stereo FM with RDS, using Arduino Nano, Si473x Radio IC and 1.8in TFT color display ST7735.
In tutorial we will learn how to build a DIY Arduino RC transmitter. Very often I need wireless control for the projects that I make, so therefore I built this multifunctional radio controller which can be used for pretty much everything.
The Ultimate FM Transmitter (Long Range Spybug): Have you ever wanted to broadcast your own radio station within your neighborhood? Ever get curious on where people get those "Surveillance Bugs" from spy and action movies? This small and simple FM transmitter is the toy that geeks have always want…
Art Deco FM Radio Project Using Arduino: Dear friends welcome to another Arduino project Instructable! I am very excited because today I am going to show you how I built this Art Deco style FM Radio project using Arduino. It is by far the most complex project I have ever built and also my …
FM Radio With Si4703 Breakout Board, LCD and Arduino: This project is just a small part of a bigger project I have been working on for the past couple of years (on and off). The background to this project is that a couple years back, I found a modern jukebox (iPod connection, AM/FM radio, CD player...)…
